Fecundity and fertility in female homo- and heterokaryotypes of the tumorous-head strain of Drosophila melanogaster.
HE tumorous-head (tu-h) strain of Drosophila melanogaster has been the T subject of extensive investigations (for a review of the literature see CrARDNER 1959; WOOLF, KNOWLES and JARVIS 1964). The expression of the trait depends on a semi-dominant gene at position 56 on the third chromosome and a sex-linked recessive gene controlling a maternal effect. Modifiers affecting penetrance have been d...
متن کاملViability of homokaryotypes in the tumorous-head strain of Drosophila melanogaster.
HE tumorous-head trait in Drosophila melanogaster is caused by a third chromosome gene (tu-?) showing reduced penetrance. The penetrance can be increased by a sex-linked recessive gene ( tuI ) controlling a maternal effect (GARDNER and WOOLF 1949), by polygenic modifiers (GARDNER, STOTT and DEARDEN 1952), and by high temperature during an early developmental period (GARDNER and WOOLF 1950). Whe...
متن کاملGenetic divergence among tumorous-head strains of Drosophila melanogaster.
HE tumorous-head strain (symbolized tu-h) of Drosophila melanogaster has been the subject of a large number of investigations. An introduction to the literature can be found in GARDNER (1959), WOOLF, KNOWLES and JARVIS (1964), and JOHNSON and GARDNER (1965). Abnormal head growths occur in the flies of this strain because of the presence of a semidominant gene ( tu-3) in the right arm of chromos...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولThe influence of high and low temperatures on the expression of tumorous head in Drosophila melanogaster.
N a previous paper (GARDNER and WOOLF 1949) a character expressed as I abnormal growths in the head of Drosophila melanogaster was discussed. The expression was shown to be dependent upon two genes, one sex-linked and one autosomal. The sex-linked gene ( tu-f) was shown to control a maternal effect expressed only in the presence of the third chromosome semidominant gene tu-3). The penetrance in...
